Crew Members

I'm writing a story that involves first class stewards. I have been trying to find information about where they ate; what they did during free time; what their rooms were like; etc. There don't seem to be too many articles about stewards on here and I can't find much on other sites- the stewards of the crew seem to be a largely overlooked group. Does anyone happen to have any information?

Did Titanic crewmembers back in the day really carried firearms or is it something made up by the producers of the 1997 film?
